Here is a simplified version of the game "Win an additional mark if U can!".There are two players.Each player names an integer between 1 and 4.The player who names the integer closest to two thirds of the average integer gets a reward of 10, theother players get nothing.If there is a tie (i.e., choosing the same number), each player gets reward of 5.(a) Represent this game in Normal Form. (b) Answer the following questions When player 2 chooses 4, what are the best responses for player 1?When player 1 chooses 3, what are the best responses for player 2?When player 2 chooses 2, what are the best responses for player 1?When player 1 chooses 1, what are the best responses for player 2?For player 1, is the strategy of choosing 4 strictly or very weakly dominated by another strategy? Ifso, which ones?For player 2, is the strategy of choosing 1 strictly or very weakly dominated by another strategy? Ifso, which ones?(c) What is the Nash equilibrium of this game? Find this out by applying the concept of dominated strategies to rule out a succession of inferior strategiesuntil only one choice remains.

all 4 questiion are related with PHP1) Create a two-part form that calculates and displays the amount of an employees , salary based on the number of hours worked and rate of pay that you input. Use an HTML document named paycheck.html as a web form with 2 text boxes-one for the amount of hours worked and one for the rate of pay. Use a PHP document name paycheck.php as the form handler.2) Simulate a coin tossing PHP program. You will toss the coin 100 times and your program should display the number of times heads and tails occur.3) Write a php script to generate a random number for each of the following range of values.1 to 271 to 1781 to 600Save the document as RandomValues.php4) Write a PHP script to sum and display the all the odd numbers from 1 to 75.

"Dijkstra's single-source shortest path algorithm returns a results grid that contains the lengths of the shortest paths from a given vertex [the source vertex] to the other vertices reachable from it. Develop a pseudocode algorithm that uses the results grid to build and return the actual [shortest] path, as a list of vertices, from the source vertex to a given [target] vertex. (Hint: This algorithm starts with a given vertex [the target vertex] in the grid's first column and gathers ancestor [parent] vertices, until the source vertex is reached.)"*For your algorithm, assume that grid is the name of the results grid produced by Dijkstra's single-source shortest path algorithm.*Each vertex is identified by its label/name, which is in column 1 of grid.*As the first step of your algorithm, find the name of the source vertex.*Next, get the name of the target vertex from the user.Pseudocode should avoid details through broad-stroke statements. However, it must give enough information to outline the overall strategy.In addition to showing your algorithm, answer the following questions: - In pseudocode, to find the source vertex, you can simply write: find source vertex Without providing code, explain how this would be accomplished in real code. - Did you run into any challenges? If so, what were they and how did you solve them? - Besides the given grid, did you have to use any other collection? If so, which one and why? If not, why not?
